Why not use updatable CTEs? That's what they're for.

WITH update_contact as (
INSERT INTO contacts ( contact_id, name )
VALUES ( nexval('contacts_id_seq'), 'Joe' )
RETURNING contact_id ),
new_cont_ids AS (
SELECT contact_id FROM update_contact;
),
insert_phones AS (
INSERT INTO phones ( phone_id, contact_id, phone_no )
SELECT ( nextval('phone_id_seq'), contact_id, '415-555-1212' )
FROM new_cont_ids
RETURNING phone_id
) ...

I think you get the idea. On 9.3 or later, this is the way to go.
